The White House's nominee for Director of the Central Intelligence Agency, Leon Panetta, has earned more than $700,000 in speaking and consulting fees since the beginning of 2008, with some of the payments coming from troubled financial firms and from a firm that invests in contractors for federal national security agencies, according to financial disclosures released Wednesday.

Mr. Panetta received $56,000 from Merrill Lynch & Co. for two speeches and $28,000 for a speech for Wachovia Corp., according to disclosures released ahead of Thursday's scheduled Senate hearing on Mr. Panetta's nomination.

"We anticipate that [Thursday's] hearing will focus on the substance of Mr. Panetta's views about how to strengthen our intelligence gathering and keep our nation safe, as all of Mr. Panetta's income and investments have been thoroughly reviewed by the Office of Government Ethics," White House spokesman Tommy Vietor said.
